    Default Leaf Splitting

    Orchid growers are sometimes plagued with leaf splitting in their collection, particularly with phalaenopsis, paphiopedilums, and occasionally cattleya-types and others.

    There are a variety of theories intended to explain the reason for such issues, many relating to humidity, light levels, dehydration followed by heavy watering, and watering frequency, but I believe there may be a nutritional basis, either alone or in conjunction with other parameters, so the goal of this is to collect a wide range of experiences to see if there is any correlation.

    If you have an interest and can spare a couple of minutes, would you please submit your "leaf splitting" experience using the form here?

    I'll let it run for a week or more before I tabulate and share the results.

    Ray, I have one with a split leaf. However, it was a rescue in bad shape and the leaf split about a week after I got it. I don't know that answering the questions on your form will help you. It was very dry when I bought it, but apparently had been very wet at one time as it had root rot. The leaf did split after I repotted it - about a week after I got it.

    I read somewhere on the internet that split leaves are caused by over-fertilizing.
    I have a phal with split leaves. New leaves appear normal, but after they grow to certain size, the tip of the leaf would split. I did over-fertilize it last year though, used all the possible stimulators too as was desperate not to lose it. But honestly it's hard to believe it can last for over a year. Will continue watching it grow and see if it changes any soon or ever.
